| Number | Percent | Number | Percent | |
| Total | 5,224 | 100.0 | 5,224 | 100.0 |
| Less than 1,500 | 25 | 0.5 | 68 | 1.3 |
| 1,500-2,499 | 219 | 4.2 | 300 | 5.7 |
| 2,500 or more | 4,980 | 95.3 | 4,856 | 93.0 |
NOTES: A contingency table analysis of the low-birth-weight experience of matched pairs yielded a chi-square = 26.8, df = 1 (p < .001). Only single live born infants are included; twins, triplets, etc., are excluded. Percents are rounded independently and may not add to totals.
